4. None of these

plz help me fast ​

Answer 1

Answer:

1. y=x+4 and x=10-y

hope it helps

Answer 2

Answer:

1.y=x+4 and x=10-y

Explanation:

let the no. of boys be x

and no. of girls be y.

Number of total students=10

x+y=10

Therefore

Number of girls =(Number of boys) + 4

y=x+4

x-y=-4

Therefore,

The required pair of equations are

x+y=10;x-y=-4.
